Quality of life and aphasia. Multicentric standardization of a questionnaire.

AIM: It is important to assess aphasics' quality of life in order to plan a rehabilitation treatment. To date such a tool is still missing for Italian patients. This paper reports normative data of the Italian version of SAQOL-39, a British questionnaire aimed to assess aphasics' quality of life. It consists of 39 items, divided into 4 subdomains (Physical, Communication, Psychosocial and Energy). METHODS: Forty-two patients coming from 3 different Speech Therapy Services were enrolled. All patients completed speech therapy before examination. They were submitted to the Italian SAQOL-39 and 2 screening tests for aphasia: 1) Communication Assessment Scale according Goodglass and Kaplan; 2) Franchay Aphasia Screening Test (FAST). A receptive FAST score of 7 out of 15 was used as a cut-off score for SAQOL-39 administration. RESULTS: The Italian SAQOL-39 showed good internal consistency (full scale Cronbach's alpha 0.939). Cronbach's alpha for every subdomains ranged from 0.950 (Communication) to 0.720 (Energy). Fluent aphasics gave significantly higher scores than nonfluent ones on full scale, and all out of Energy subdomains. Furthermore gravity of aphasia correlated with both full scale and Communication subdomain scores. CONCLUSIONS: In authors' opinion, the Italian SAQOL-39 shares many psychometric features with the English one. This questionnaire seems to be suitable for clinical practice.

What kind of visual spatial attention is impaired in neglect?

The distribution of spatial attention across the horizontal meridian of the visual field, as assessed by a simple reaction time (RT) paradigm, is dramatically abnormal in neglect patients. In the contralesional hemifield, RT increases sharply from centre to periphery, while in the ipsilesional hemifield, it decreases paradoxically from centre to mid-periphery. In the present study, we firstly asked whether this abnormal distribution of spatial attention is still present when patients know in advance the location of the impending stimulus, and second whether and to which extent it may be influenced by the concomitant presence of hemianopia. In Experiment 1, the stimuli were presented either predictably (blocks of same-point presentations) or unpredictably (blocks of randomised presentations) to one of several contralesional and ipsilesional field locations. As was the case for control subjects, neglect patients showed an overall RT decrease with same-point presentations. However, their abnormal contralesional RT lengthening and ipsilesional speeding were still present. In Experiment 2, the trials were blocked to same-hemifield presentations. In the ipsilesional field condition, neglect patients with and without hemianopia showed the same distorted distribution of attention favouring mid-periphery over central field locations. Two conclusions can be drawn from these experiments: first, the bulk of the abnormal deployment of spatial attention in neglect patients is related to an impairment of exogenous attention which cannot be compensated for by a spared endogenous control. Second, hemianopia does not affect the paradoxical speeding up of RT typically found in the mid-periphery of the ipsilesional field of neglect patients.

Aphasia quality of life: reliability of the Italian version of SAQOL-39.

AIM: In recent times there has been an increasing interest in assessing the quality of life (QOL) in stroke clinical trials. To our knowledge, an Italian tool suitable for this purpose is still missing. So we adapted to Italian language the Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39), that is a British questionnaire recently validated with aphasic subjects. The aim of this paper is to validate our version of SAQOL-39. METHODS: To determine the matching of our version, we requested a native English speaker to translate the Italian version into English. Twelve patients (7 male, 5 female; mean age 66.4 years) were submitted to our test. All subjects were interviewed twice by 2 raters, at 24 h of distance. Neither examinator knew results of the other interview. Statistical analysis was performed by determining Cronbach's a and the intraclass correlation coefficient (ICC). RESULTS: Comparing the original SAQOL-39 to the English translation of our Italian version, we found only a low percentage (10%) of minimal semantic variations. As for test-retest reliability, ICC for global score was 0.898 (ICC(2,39)). ICC range for SAQOL-39 subdomains was 0.816 to 0.969. Cronbach's a for full scale scores was 0.916 (subdomains ranged 0.767 to 0.976). Results seem good as for usefulness, reliability and acceptability of the Italian version of SAQOL-39, like the original version of this test. CONCLUSIONS: Our Italian version of SAQOL-39 seems suitable for clinical use. A multicentric study aiming to compare our data to original English ones is in progress.

A new case of atypical cerebral dominance.

A.V., a 73-year-old right-handed man, developed right hemiplegia and hemi-hypoaesthesia following a cerebrovascular accident. A large, left hemispheric lesion was revealed by CT scan but, despite this, the patient did not show any language impairment in either Italian or English (which he spoke fluently). However, he did show right visual neglect and visuo-spatial deficits, a neuropsychological picture that usually follows lesions to the non-dominant hemisphere. Given these clinical data, A.V.'s cerebral organisation seems to be reversed. This and previous cases reported in the literature are discussed.

A case of unilateral opercular syndrome associated with a subcortical lesion.

A patient who developed a unilateral opercular syndrome following a cerebrovascular accident is described. Computed tomography showed that the lesion did not affect the opercular cortex, but involved deep white matter and the head of the caudate nucleus of the left hemisphere. Persistent hypophonia and transient aphasia were associated. Comparison with previous cases is discussed.

Selective impairment of the graphemic buffer in acquired dysgraphia: a case study.

The case of an Italian dysgraphic patient (S.E.), who showed a deficit of both written and oral spelling capacities, without significant differences between words and nonwords, is reported. The pattern of the patient's performance was identical on writing to dictation, delayed copying, and written naming. The most common category of errors was single-letter deletions, and errors were predominantly made in medial positions. Stimulus length appeared to be the single factor that most affected performance. This pattern is consistent with the hypothesis that S.E.'s spelling disorder results from selective damage of the Graphemic Buffer. The case is discussed in relation to current functional models of writing and is compared with similar cases reported previously.

Post-traumatic transient amnesias.

Temporary memory disorders following closed head injuries are presented, with special remark on the cases of transient global amnesia (TGA) triggered by head trauma. The relationship with idiopathic forms of TGA is discussed.

Unilateral visual agnosia.

A case of unilateral visual agnosia for all types of stimuli limited to the left visual hemifield and associated with a right occipital temporal vascular lesion is reported. Questions raised by this case of hemiagnosia as compared to previous ones are discussed.

Discriminant analysis of WAIS results in different types of dementia and depressed patients.

A Multivariate Analysis of Covariance and Discriminant Analysis were carried out on complete WAIS profiles obtained from three groups of demented patients: Multi-Infarct Dementia patients, Senile Dementia of Alzheimer Type patients, and Alcoholic Dementia patients. A group of middle-aged Depressed patients was also included. WAIS did not differentiate among dementias, but Picture Completion and Block Design subtests proved to be effective in differentiating dementia from depression.
